[Q] Bluetooth problem after upgrade - Desire General

When I bought new car in May, Hyundai ix35, everything between Desire and car worked flawlessly: paired within 1 minute, phone book transfered in 3-5 minutes ?btw, why it had to transfer whole phone book everytime?? and reconnected automaticaly after out of range or car stereo off/on, voice dialing ...
BUT, after upgrading to android 2.2 I'm experiencing a lot of problems: no automatic reconnection, can connect only when car is started and phone bt after that, phone keep thinking that is connected even car is miles away, phone (application) restart after almost every call when bt is connected. I've tried with unpairing and pairing devices again, but there is no difference.
Car didn't have sw upgrade only phone.

EVO, Bluetooth constantly disconnecting

Before I rooted my Evo and upgraded to 2.2 all in the same day I had no issue with BT and my car connection.
Now my phone will connect to my car via BT, but then disconnect within 30 seconds. Then the car fails to reestablish a connection with the phone (even if I cycle the car, off and on) unless I cycle the BT off and on , on the EVO). After cycling the BT on the phone, the car will reconnect, only to lose it again within 30 seconds. ?
Ideas or thoughts?. Is this a hardware issue with the phone (doubtful) or a 2.2 issue or is something not right between 2.2 BT stack and the car BT system
The vehicle is a Ford with the "Sync by Microsoft".

same problem here. using Fresh 3.40.1
driving me nuts... i haven't tried it yet as I have 4G in my area but I hear Cynogen works...
Google and HTC know there is an issue in 2.2 with Bluetooth intermitent disconnects. The 2.2.1 supposedly fixes this but, it is only available to a few phones.

[Q] M8 Bluetooth Disconnect in 2014 Civic

Hi All,
I recently bought a 2014 Civic Si and I've been getting strange disconnects from the Bluetooth Hondalink. Initially the phone would disconnect every 30 seconds or so and I realized it was because I had to allow the phone to share the phone book. That seemed to solve the constant, repetitive disconnects. Since then, when I start the car, the phone will connect, but then disconnects as soon as the phone functionality or the media functionality is accessed by the car the first time. If I then manually reconect the phone via Bluetooth it will stay connected just fine. After manually reconnecting I can stream audio or take/make phone calls no problem.
As an example, I start the car, the phone and Hondalink connect, Pandora will automatically start playing through the car audio. After about 10 seconds, it disconnects and then I hear Pandora from the phone speakers. I manually reconnect the phone to Hondalink and it stays connected, all works good after that.
Any ideas what might be happening on the initial connection?
My M8 is a carrier unlocked version ordered from HTC. I use it on AT&T.
Thanks for any ideas,
Lenny

I would delete it out of your phone, and delete the phone out of your car, start over the procedure and see if that helps.
I'm having Bluetooth problems in my civic 2012..
Bluetooth streaming works fine, but calls disconnect and reconnect to the cars Bluetooth.
I've deleted the devices both from the car and phone, but it still disconnects and reconnects. Has anyone found a fix for this?
I know this doesn't help you at all, but I have a 2015 Civic and I have this exact same problem. HTC One M8, starts up fine and then disconnects. I have to manually choose a device to connect to and then I'm good to go for the rest of the time.
Annoying.

Watch and Bluetooth Headset disconnect from iphone

Hello All,
So I just bought my Huawei Watch 3 days ago, I have an iPhone running iOS 10 the latest version, opened the watch, paired it and worked fine.
At the same time, I was connecting my iphone to a bluetooth headset, as well as being connected with my watch, and worked fine.
Suddenly on the day after, whenever I connect my watch to the phone and the phone to the Bluetooth headset, it works for sometime and then all bluetooth devices are disconnected ! Including the watch and the bluetooth headset. Sometimes it works fine as long as i dont access my phone, i mean the music is working in the background until i turn on the iphone screen and instantly it disconnects from the watch and the headset.
Any ideas ???
Thanks.

Bluetooth issues

I just bought a z2 about a week ago. Been a great phone so far. It updated to Oreo as soon as I turned it on.
There is one issue. Bluetooth. When I originally connected it to my Alpine cd-hd148bt, it would stream music, but the phone profiles would not load. So I updated the bt firmware on the headunit. Now if I restart the headunit, it will connect with all the appropriate icons for audio and phone. If I start an audio app, it says playing, the head says playing, but there is no sound. After a couple of minutes, the entire phone will disconnect from the deck. It won't come back until I pull the faceplate and reboot the headunit. Even turning off the car and powering off won't get the bt to work.
Does anyone have any ideas? I love listening to Pandora, and my city has a hand free law, so I would love to have the phone working also.
PLEASE HELP!! I will owe you a cookie.
Thanks
Edit: unlocked bootloader and magisk 15.2.
im also having issues with bluetooth, since headset will disconnect from time to time and while streaming music to a bluetooth speakers (bose, harman, jbl, chinese, etc) audio will cut from time to time, until bluetooth connection drops an will have to restart phone in order to connect again
I am also having Bluetooth issues, keeps disconnecting from my headphones, or connects and doesn't stream. Supposedly with Oreo Bluetooth had been updated to version 5.

OTA May 2018 Update + Car Bluetooth Music issues

Hi all,
Has anyone experienced any weird Bluetooth issues after installing the latest May OTA update (OPM1.171019.011-RZR-180509.5038)? I've realized that the BT controls on my 2015 Nissan Sentra no longer work properly. It doesn't automatically connect to BT anymore and no track information shows on the head-unit. The weird thing is that I CAN get music to play, at least.
I just wanted to know if I happened to be losing my mind after numerous reboots and re-pairing between the car and the phone.
Same for me. I can delete it. Pair it again and it works. Next time I get in the car it won't reconnect.. worked fine before the update at the weekend.

It's a fire an miss actually. Sometimes it reconnects automatically with the car's unit (alpine aftermarket) and sometimes it doesn't. I had noticed that if I get in the car for the 1st time today (for ex), it won't reconnect back and i have to cycle around the input in order to "kickstart" the reconnecting process. If I make a stop along the way, stop the car, get out (thus interrupting the connection) and getting back after a while, it will reconnect automatically without any issues. I'm not even taking it out of my pocket. But this scenario is happening since day one, not necessarily from the last update.
On the other hand, I got a smartband (coincidentally after the last update) and now, while the smartband is connected via BT, when I turn on my BT wireless headphone adapter, it won't re-connect anymore (simultaneously with the smartband) and if it does, it's without media playback. As a workaround, I have to 1st turn off the smartband, clear the BT of any active connection (And also any other device with media playback capabilities), turn on the BT adapter so it will connect full, then turn the smartband back on. And not always works like this.
So, I do have on an off issues with the BT stability and connections with various devices, not just car unit.
Strangely though my smart watch connects no problem and the stereo in my motorhome was connecting at the weekend. It's just the car ( a Vauxhall Astra) that refuses to connect unless I delete and re pair....

I can't get music to play with Spotify or YouTube. The phone connects fine, shows song info but just won't play no matter what I try.
The weird thing is that calls work perfectly. Sound through car speakers and mic works. Just doesn't want to play music.
I've tried unpairing, re-pairing, deleting, even factory reset on both phone and stereo. Worked fine before the 8.1 Oreo update. (I'm on 3 UK handset).
Im having issues as well, it will connect the first time when I manually connect the phone and stereo to MyLink. It will say connected but (No Media) so i try to pair the media and it disconnects my phone from BT and then i have to delete device and re connect device manually. As well if i leave the vehicle or turn it off then it will disconnect. Not just my vehicle but the other showroom vehicles do that as well. Can someone let me know if there is a bluetooth upgrade or a firmware upgrade that can fix this problem? is there anything that we can do for this let me know. Thanks!!
I am having the same issue in my bmw.
I can delete the phone and re-pair... But it sucks having to do that every thing.
also having issues as well. It connects to my headphones and the after market HU in my truck but it will not connect at all to the factory HU in Genesis Coupe. I have tried to delete and re pair and still nothing.
So currently it all works for me with the latest update. It definitely takes a little bit longer than normal though. Not sure how long some of you waited, but compared to my old phones it feels like an eternity during the time it doesn't connect. I also use a smartwatch and it is always connected to that. If you guys need or want any files, let me know. I'm currently waiting for a usb-c to usb-a cable in the mail, so once that is here I can try to help.
I think this is all more of an Android issue. I was having most of the exact same issues mentioned here on my LG V20 on Oreo.
I just for a Razer Phone 1 off eBay this week. I did the Pie update and within a day, the bluetooth issues have returned. Sometimes phone won't connect to car stereo - sometimes reboot stereo, sometimes toggle phone bluetooth off/on, or sometimes just wait 10-30 seconds. Doing the same showing info on car stereo display, but no audio transmitted. I also had similar issues using a OnePlus 3 with both Dirty Unicorns and Resurrection Remix Pie ROMs. I was beginning to think it was my car stereo until I read the comments on this thread. Seeing so many others having the exact same issues on factory and aftermarket stereos (mine is an aftermarket), and knowing it's happening on different devices and both Oreo and Pie , I'm thinking it's an Android 8 and 9 issue.
